DNP mounting issue

[Marc Kleine-Budde]

Hi!

I'm using linux-2.4.21 together with mtd from 'Mon Jun 23 17:45:34 CEST 2003'
The hardware is SSV's DNP-486 (=2 MB flash).

When booting the jffs2 filesystem on the mtd cannot be mounted,
surprisingly it works with an unpatched linux-2.4.21 out of the box.

I've attached the bootingmessages from both kernels....


hope someone can help
	Marc
